I am developing web based application in Java [GWT]
I am facing problem with TwitterException.
I used valid credential.
Twitter twitter = new Twitter(myTwitterId, myTwiterPwd);
when I call twitter.getFollowers() method
I got following Error Message
twitter4j.TwitterException: 401:Authentication credentials were missing or incorrect.
<?xml version="1.0" encoding="UTF-8"?>
<errors>
<error code="53">Basic authentication is not supported</error>
</errors>

Please provide me Easy solution for the same
Hope for the best co-operation from your side
Thanks in advance !!!
Yes, your authentication is not working because Twitter made some recent changes
regarding how it lets 3rd party code authenticate.
In other words, Basic authentication has been turned off for the API.
As Allain mentions, oAuth is the way to go.
